# Frameless window A frameless window is a window that has no chrome. ## Create a frameless window To create a frameless window, you only need to specify `frame` to `false` in [BrowserWindow](api/browser/browser-window.md)'s `options`: ```javascript var BrowserWindow = require('browser-window'); var win = new BrowserWindow({ width: 800, height: 600, frame: false }); ``` ## Draggable region By default, the frameless window is non-draggable. Apps need to specify `-webkit-app-region: drag` in CSS to tell atom-shell which regions are draggable (like the OS's standard titlebar), and apps can also use `-webkit-app-region: no-drag` to exclude the non-draggable area from the draggable region. Note that only rectangular shape is currently supported. To make the whole window draggable, you can add `-webkit-app-region: drag` as `body`'s style: ```html ``` And note that if you have made the whole window draggable, you must also mark buttons as non-draggable, otherwise it would be impossible for users to click on them: ```css button { -webkit-app-region: no-drag; } ``` If you're only using a custom titlebar, you also need to make buttons in titlebar non-draggable. ## Text selection One thing on frameless window is that the dragging behaviour may conflict with selecting text, for example, when you drag the titlebar, you may accidentally select the text on titlebar. To prevent this, you need to disable text selection on dragging area like this: ```css .titlebar { -webkit-user-select: none; -webkit-app-region: drag; } ``` ## Context menu On some platforms, the draggable area would be treated as non-client frame, so when you right click on it a system menu would be popuped. To make context menu behave correctly on all platforms, you should never custom context menu on draggable areas.
